I have recently started a shopping website and wanted to have a price comparison feature on it. The price comparison feature would essentially take information from numerous websites such as walmart.com, newegg, amazon, best buy, etc when given access to each API of those respective websites. I was wondering if this is a feasible module to create. There is a module somewhat like this already in existence. It is from the website called Pricegrabber.com. I am unsure how they go about getting this information and whether they use API information in this module, but I figured it would help anybody reading this to understand what I am talking about. If you could provide me with any information about this I would really appreciate it. I am also not sure if this is the appropriate section to post this here as I am new and not very well versed in programming. Thanks for your help!
